How to adjust the tightness of three-jaw pneumatic chuck of CNC lathe

The clamping force of the pneumatic chuck can be adjusted by adjusting the air pressure regulating valve of the chuck.

If the clamp cannot clamp the workpiece, loosen the screw on the clamp.

Move a few pitches and tighten the screws.

Remember: the number of teeth moved by the three jaws must be equal, otherwise the workpiece cannot be clamped correctly.
